According to my crystal ball, the reason for this is that Bob had the
file open in his favorite text editor when he did the update.  Some time
later, Bob saved the file from the editor, replacing the merged copy
that CVS had created with his original version without any of Joe's

You should be able to recover by having Bob redo the merge manually:

        cvs up -r1.2.2.3 -r1.2.2.4 helper.c

However, some versions of CVS "know" that helper.c should already
contain those changes and so don't do anything for that command.  In
that case you can use cvs diff and patch:

        cvs diff -r1.2.2.3 -r1.2.2.4 helper.c | patch
